Driving in Special Conditions WithFour-Wheel drive (4WD)
Note:Use of the 4WD system in slippery,deep snow, and sand drive modes on drysurfaces could produce some vibration,driveline bind up, or excessive tire wear asthese drive modes are intended for slipperyand loose surfaces.
Note:The design of 4WD vehicles are fordriving on sand, snow, mud and rough roadsand have operating characteristics that aresomewhat different from conventionalvehicles, both on and off the highway.
Basic Operating Principles in SpecialConditions
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•Be extremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.
If Your Vehicle Goes Off the Edge of thePavement
•If your vehicle goes off the edge of thepavement, slow down, but avoid severebrake application, ease the vehicleback onto the pavement only afterreducing your speed. Do not turn thesteering wheel too sharply whilereturning to the road surface.
•It could be safer to stay on the apronor shoulder of the road and slow downgradually before returning to thepavement. You could lose control if youdo not slow down or if you turn thesteering wheel too sharply or abruptly.
•It often could be less risky to strikesmall objects, such as highwayreflectors, with minor damage to yourvehicle rather than attempt a suddenreturn to the pavement which couldcause the vehicle to slide sideways outof control or rollover. Remember, yoursafety and the safety of others shouldbe your primary concern.
If Your Vehicle Gets Stuck
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou leave your vehicle. Failure to followthis instruction could result in personalinjury or death.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.

If your vehicle gets stuck in mud or snowyou can rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts, in a steady pattern. Presslightly on the accelerator in each gear.
If your vehicle comes with AdvanceTrac®with Roll Stability Control™, it could bebeneficial to disengage the AdvanceTrac®with Roll Stability Control™ system whileattempting to rock the vehicle.
Note:Do not rock the vehicle if the engineis not at normal operating temperature ordamage to the transmission could occur.
Note:Do not rock the vehicle for more thana few minutes or damage to thetransmission and tires could occur or theengine could overheat.
Emergency Maneuvers
•In an unavoidable emergency situationwhere a sudden sharp turn must bemade, remember to avoid"over-driving" your vehicle (forexample, turn the steering wheel onlyas rapidly and as far as required toavoid the emergency). Excessivesteering can result in less vehiclecontrol, not more. Additionally, smoothvariations of the accelerator and/orbrake pedal pressure should be utilizedif changes in vehicle speed are called
for. Avoid abrupt steering, accelerationor braking which could result in anincreased risk of loss of vehicle control,vehicle rollover and/or personal injury.Use all available road surface to returnthe vehicle to a safe direction of travel.
•In the event of an emergency stop,avoid skidding the tires and do notattempt any sharp steering wheelmovements.
•If the vehicle goes from one type ofsurface to another (i.e., from concreteto gravel) there is a change in the waythe vehicle responds to a maneuver(steering, acceleration or braking).Again, avoid these abrupt inputs.
Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowlyand avoid spinning the wheels.
Avoid excessive speed because vehiclemomentum can work against you andcause the vehicle to become stuck to thepoint that assistance could be requiredfrom another vehicle. Remember, youcould be able to back out the way youcame if you proceed with caution.
Mud and Water
If you must drive through high water, driveslowly. Traction or brake capability couldbe limited.
Note:Driving through deep water coulddamage your vehicle.
When driving through water, determine thedepth; avoid water higher than the bottomof the hubs (if possible) and proceedslowly. If the ignition system gets wet, thevehicle could stall.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn. Have your vehiclechecked. If the vehicle has continuousvibration or shudder in the steering wheelwhile braking, have your vehicle checked.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. Wet brakes result in reducedbraking efficiency. Gently press the brakepedal a few times when driving from a carwash or standing water to dry the brakes.
See Cleaning the Wheels (page 344).
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement. If none are found and thecondition persists, have your vehiclechecked. If your vehicle has to be towed,we recommend that you contact aprofessional towing service.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional.
If the warning lamp does not illuminateduring start up, remains on or flashes, thesystem may be disabled. Have the systemchecked. If the anti-lock brake system isdisabled, normal braking is still operational.
See Warning Lamps and Indicators(page 105).
Note:Indicators vary depending on region.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or if it begins to flashat any time except the time during applyingor releasing the parking brake, have thesystem checked.
Regenerative Braking System
This feature simulates the engine brakingof an internal combustion engine andassist the standard brake system whilerecovering some of the energy of motionand storing it in the battery to improve fueleconomy. The standard brake system isdesigned to fully stop the car ifregenerative braking is not available.During regenerative braking, the motor isspun as a generator to create electricalcurrent. This recharges the battery andslows the vehicle. Once the acceleratorpedal is released, the motor changes froman energy user to an energy producer.

2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingBrakesE67020 E270480 E67024

When you release the accelerator pedal orpress the brake pedal, the brake controllerautomatically detects the amount ofdeceleration requested and optimizes howmuch of the deceleration will be producedby regenerative braking. The remainingportion is generated by standard frictionbraking. When the battery is almost fullycharged, the amount of regenerativebraking is limited to avoid overcharging,and the requested deceleration isproduced by standard friction brakingalone.
Regenerative braking does not take theplace of the standard friction brakes; it onlyassists them. Regenerative braking isdesigned to interact with the anti-lockbrake system. Regenerative brakingdisables when the anti-lock brake systemis activated or the battery is fully charged.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and may travel further.Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.
ELECTRIC PARKING BRAKE
WARNING: Apply the parking brakeand shift into park (P) before leavingyour vehicle.
WARNING: If you drive extendeddistances with the parking brake applied,you could cause damage to the brakesystem.
WARNING: The electric parkingbrake does not operate if the vehiclebattery has run out of charge.
Your vehicle has an electric parking brake.You operate it with a switch instead of alever. The switch is on the center consoleor to the left-hand side of the steeringwheel, on the lower part of the instrumentpanel.

HILL START ASSIST
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake.
WARNING: You must remain inyour vehicle when the system turns on.At all times, you are responsible forcontrolling your vehicle, supervising thesystem and intervening, if required.Failure to take care may result in the lossof control of your vehicle, seriouspersonal injury or death.
WARNING: The system will turnoff if a malfunction is apparent or if yourev the engine excessively. Failure to takecare may result in the loss of control ofyour vehicle, serious personal injury ordeath.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system is active, your vehicleremains stationary on the slope for two tothree seconds after you release the brakepedal. This allows time to move your footfrom the brake to the accelerator pedal.The system releases the brakesautomatically once the engine hasdeveloped sufficient torque to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, for example from a car park ramp,traffic lights or when reversing uphill intoa parking space.
The system activates on any slope thatcauses your vehicle to roll.
Note:There is no warning light to indicatethe system is either on or off.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed and shift intofirst gear when facing uphill or reverse(R) when facing downhill.
2.If the sensors detect that your vehicleis on a slope, the system activatesautomatically.
3.When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away forabout two to three seconds. This holdtime automatically extends if you arein the process of driving off.
4.Drive off in the normal manner. Thesystem releases the brakesautomatically.
Note:When you remove your foot from thebrake pedal and press the pedal again whenthe system is active, you will experiencesignificantly reduced brake pedal travel. Thisis normal.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System Off
When you switch the system off or on, amessage appears in the informationdisplay showing system status.
You can switch the system off by using theswitch.
Using a Switch (If Equipped)

PRINCIPLE OF OPERATION
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo loudspeakers mayinterfere with and adversely affect theelectronic stability control system. Installany aftermarket stereo loudspeaker asfar as possible from the front centerconsole, the tunnel, and the front seatsin order to minimize the risk of interferingwith the electronic stability controlsensors. Reducing the effectiveness ofthe electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It’s always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator’s ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death. If yourelectronic stability control systemactivates, SLOW DOWN.
The system automatically turns on eachtime you switch the ignition on.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the systemsapplies higher brake forces.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Roll Stability Control
The system enhances your vehicle’s abilityto prevent rollovers by detecting yourvehicle’s roll motion and the rate at whichit changes by applying the brakes to oneor more wheels individually.
Curve Control
The system enhances your vehicle’s abilityto follow the road when cornering severelyor avoiding objects in the roadway. CurveControl operates by reducing engine powerand, if necessary, applying brakes to oneor more of the wheels individually.
